AMD HD7XXX Series - Latest leaked details - Chiphell

[mattkosem]

AMD Rebrand HD5770 -> HD6770 and now they rebrand it as HD7770 ?
Oh come on give me a break !! That's BAD !!

How is that any worse than 8800GT 512>9800GTX>9800GTX+>GTS250? I'm assuming AMD is doing it for the same reason Nvidia does.

He only said that was bad, not less bad that what nvidia did. Let's not fall again in the same place please...

Some improvements in either more performance or less power would be welcome.

[iddqd]

I'm pretty sure AMD (or nvidia, for that matter) themselves don't really much care for it either - the pressure to rebrand mostly comes from big box OEMs like Dell, HP, Lenovo, etc... they'd very much like to keep putting the same el cheapo die in their boxes, but "keep up" with the latest gen at the same time . Can't have it all, so the next best thing is to keep up with the naming scheme.

Either way, since when does XS give a rat's ass about low end crap?

[Manicdan]

if the 6770 goes to 7770, that sure does not leave much room for a 7970 to beat a 6970 now does it.

Not all of us have megatons of cash to blow on new top of the line hardware every 6 months.

[iddqd]

While true, it is almost always better to buy a used top of the line card that's 1 or 2 generations old, than to buy the current low-end pos. We even have a pretty good fs/ft section on this very forum!

I disagree, stuff like the 4850 when it came out were both very affordable and better options than the previous high end imo

that and the 8800GT were the best perf/dollar and offered an incredible shelf life for picture quality.
the 5850 was another since its launch price stayed for a year, and now a 6870 is still only like 30% cheaper, being 2 years later.

[AliG]

Yeah the was definitely a time when the performance market offered the best of both worlds. For a reasonable price we got previous high end performance.

I think we'll see that again once the new wave of architectures come about. I don't see how AMD or Nvidia can realistically do another 8800gt type move where things currently stand regarding TSMC's manufacturing problems - though I do wonder what's holding them back from just adding more shaders in the time being (like how AMD went 320 -> 800 -> 1600). With all this being said, it's pretty remarkable to think about what NV did with the 8800gtx and how long its shelf life was. That was one of the few instances I can think of a company getting it perfectly right the first time around.

n850 is 2nd to highest end possible? How's that low-end? Try a 4350.

looks like they'll be hot or want us to overclock!

Most likely it will be on the professional lineup.
Will have to wait and see about the desktop.

[Final8ty]

planning on launching desktop HD7000 GPUs in January, and SemiAccurate just got a few more bits about them. There isn’t much new, January launch for Tahiti XT, followed by Tahiti Pro a month later, then Pitcairn XT in March, Pro in April.

The cards themselves are known as GNC (Graphics Core Next), Southern Islands, or HD7000, depending on who you talk to. All of them are made on TSMC’s 28nm process, and are cousins to the laptop lines we told you about earlier. Pricing is tentatively set for around $500 for the top Tahiti part, $400 for the Pro, $300 for Pitcairn XT, $200 for the Pro, all subject to much change and our minor but patented SPMOODT(TM)(R)(C)(P) (Source Protecting Minor Obfuscation Of Data Technology).

The new tidbit? 384-bit memory bus, that means 3GB cards. Whoopee, you can now bump the AA setting 1x more on your six 30″ 4Mp panels for Eyefinity gaming. It can’t come soon enough. Things are about to get even more silly.S|A

[iMacmatician]

So does that mean no XDR2 (not that it was likely before we knew this)?

[Manicdan]

384bit bus tells me one thing

these will be large chips. i doubt they would go as big as fermi, but its gotta be bigger then cypress. hopefully they wont come out burning hot and underclocked like fermi did either.

[AliG]

n850 is 2nd to highest end possible? How's that low-end? Try a 4350.

Since when does a 4350 cost as much as a used high end card though? Even when the 5870 first came out, a used 8800 ultra went for well more than $100, easily performance segment pricing if not more (got my 4850 for $150 when it came out). That's a non sequitur argument on your part.

[iMacmatician]

Agreed. I wouldn't be surprised if it were even bigger than Cayman.

This also reminds me of that Northern Islands rumor a while ago with a roadmap containing Cayman/Barts/Turks/Caicos. They weren't too much accurate other than the names, but they did say 384-bit bus for Cayman.

[Pantsu]

The current GDDR5 chips might be too slow combined with 256-bit so it isn't far fetched that AMD would go for 384-bit, certainly not more than going XDR2. It would be interesting to see AMD make a big chip like Nvidia, but I'm not quite ready to jump on that wagon just yet.

[AliG]

I think Fermi, r600 and BD all proved that big chips are much more difficult to get right and usually end up with heat and power consumption problems. IMO i'd rather see them stick to making flexible architectures with a dual gpu high end card and continue working parallel processing coding to eliminate microstutter

[LordEC911]

Agreed. I wouldn't be surprised if it were even bigger than Cayman.

I was told smaller than Cayman. I believe someone else on the forum heard larger than 400mm2.

I would be very surprised if it ended up being larger than R600 since they need to fit two on a PCB and unless they are clocking these things low, compared to the last few generations from AMD, the power consumption would be extremely high, far too high for New Zealand.

wasnt there a news item about faster gddr5 a 4 or 5 months ago?

oh whatever, the 4850 thing is such a corner case. mostly, 2nd highest end cards were more in the $350 price bracket.

7Gbps GDDR5 was "introduced" 3 years ago next week and we still haven't seen it on any AMD or Nvidia product.
8Gbps GDDR5 was "announced" this summer. I doubt we will see it in the next year or so.

[Mungri]

Agreed - 3850, 4850, 5770, GTX 460, GTX 560 ti - all fantastic price / performance cards and very competitive with the previous high end (Almost the same performance, vastly reduced energy consumption, temperature and noise).

They were even better when used in pairs

oh whatever, the 4850 thing is such a corner case. mostly, 2nd highest end cards were more in the $350 price bracket.

You couldnt be any more incorrect with that statement.

[DeathReborn]

8Gbps GDDR5 was "announced" this summer. I doubt we will see it in the next year or so.

Can the Memory Controllers on the chips actually operate at those frequencies though? I believe that is where the biggest hurdle lies to date, although I don't know how high AMD can get theirs to run error free.
